I'm inheriting GstBin class to make an element that change fps for video stream. My plugin was generated by using gst-template and it has the default _chain() function which push data from sink pad to src pad.
So I decide to remove this function. Then, the pipeline using gst-launch still run but nothing come out to videosink.
I've checked other element that inherited from GstBin and seem all of them do not have _chain() function.

So, what do I need to do when inherit GstBin, mean: which methods are needed to have. What's replaced for _chain() function ?


Cheers !
